Application filed January 2, 1906. Serial No. 294.206.

Toall'wh/om it may concern.-

Be it known that 1, JOHN H. KANE, a citizen of the United States, residing at New Brighton, in the county of Beaver and State of Pennsylvania, have invented a new and useful Violin-Bow, of which the following is a specification.

This-invention relates to violin-bows, and has for its object to provide improved means for-connecting the hairs to the head and also to the frog in a simple and expeditious manner.

The invention consists in the combination and arrangement ofparts, as will be hereinaftermore fully described, shown in the accompanying drawings,and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view of a violin-bow embodying the features of the present invention. Fig. 2 is an enlarged longitudinal sectional view taken through the frog and the adjacent portion of the stick. Fig. 3 is adetail perspective view of the elements of the frog detached. Fig. 4 is a detail sectional view taken through the head of the stick. Fig. 5 is a perspective view of the head and. the hair-attaching elements removed therefrom. Figs. 6 and 7 are detail sectional views showing different manners of assembling the head and the stick. Fig. 8 is a cross-sec tional view on the line 8 8 of Fig. 2. Fig. 9 is a'detail perspective view of the band applied to the rear end of the set of hairs.

Like characters of reference designate corresponding partsin each and every figure of the drawings.

The stick 1 of the present bowis of the usual or any preferred form, and while it may be made ofwood Iprefer to form the same tubular, as clearly indicated in Figs. 1 and 2 of the drawings, and to have the intermediate portion of the stick ribbed or corrugated, as at 2, so as to stiffen and strengthen the tubular stick. Any suitable material may be employed in the production of the stick-as, for instance, aluminiumalthough any character of manufactured material may be used.

The head 3 of the stick is of the usual form and is provided in its outer end with a socket 4. The hairs 5 are bound at their forward ends by a metallic band 6, which is corrugated or roughened upon its interior and pressed snugly upon the hairs. The forward ends of the hairs are received in the socket 4, there being a follower 7 fitted in the socket in rear of the hairs and one side of the socket being intersected by a threaded opening 8 for the reception of a set-screw 9, which impinges against the follower 7, the latter being provided with a seat or socket .10 for the reception of the inner end of the screw. It is preferred to have the outer end of the screw flush with the exterior of the head, so as not to offer a projection, the outer end of the screw of course having a screwdriver seat to enable the convenient removal of the screw when' ever desired. It is preferred to locate the band 6 within the back of the socket 4 and to have the follower 7 bear against the hairs, with its inner edge lapping the adjacent edge of the band 6, so as to effectually prevent the hairs from being pulled out of the socket, while at the same time the hairs may be removed by loosening the screw 9 to enable the withdrawal of'the hairs.

At the rear end of the stick there is a 'frog 11 of the usual form, which is provided in one edge with a longitudinal groove or channel 12 to receive the stick, and in this groove or channel is a projection 13, having a threaded opening 14, whereby the projection forms a nut which is designed to pass through a longitudinal slot 15 in the rear end of the stick and enter the interior of said stick. A threaded stem or retaining member 16 is designed to enter the rear open end of the stick and engage the nut 13, so as to hold the frog upon the stick and to adjust the same longitudinally thereof. At the outer end of the threaded stem there is a head 17 to engage the rear end of the stick and limit the inward movement of the stem, this head forming a convenient finger-piece for rotating the stem. The inner end of the stem is flattened to form a wedge-shaped screw-driver blade, which is designed to be used for applying and removing the screw 9 when the stem is removed from the stick. The frog 11 is solid and provided with a longitudinal passage 19, which intersects the front and rear ends of the frog. The rear half of this passage tapers forwardly, and its front half tapers rearwardly, it being proposed to pass the set of hairs 5 forwardly through the rear end of the passage 19 until the metallic band 20 upon the rear end of the set of hairs becomes wedged in the narrow middle ortion of the passage. As a further means or holding the set of hairs to the frog said frog is pierced transversely by a threaded opening 21, which intersects the grooved edge 12 and communicates with the passage 19, there being. a head-.

moving the threaded stem 16, which latter may then be employed as a screw-driver for removing'the screw 22.

While the head-3 has been shown integral with the. stick 1 in Figs. 1, 4, and 5 of the drawings, it may be made separate and attached to the stick, as shown in Fig. 6, wherein the head is provided with a socket 27, which is either smooth or threaded, and the forward end of the stick is provided with a reduced pin or extension 28, fitted in the socket 27.

In the embodiment shown inFi'g. 7 of the drawings the head 3 is provided with a shank 25, preferably threaded and received within the open front end of the tubular stick 1.

Having fully described the invention, What is claimed is 1. A violin-bow having its head provided with a socket, a set of hairs having a band embracing the same and fitted in the socket,

a follower fitted in the socket to bear against the hairs and lap the outer edge of the band, and a set-screw piercing the head for engagement with the follower to clamp the latter against the hairs.

- 2.. A violin-bow comprising a tubular stick having a longitudinal opening in the rear end thereof and a longitudinal slot intersecting the opening, a frog having a fixed nut extending through the slot and working in the opening of the stick, a threaded stem fitted in the opening in the stick and engaging the nut to retain the frog upon the stick, the frog being provided with an opening for the reception of a set of hairs, and a set-screw piercing the frog for engagement with the hairs, the head of the set-screw being covered by the stick when the frog is removable therewith.

3. A violin-bow comprising a tubular stick having a longitudinal opening in the rear end thereof and provided with a longitudinal slot intersecting the opening, a frog having an opening to receive a set of hairs and provided with a nut extending through the slot and working in the opening of the stick, a hairengaging set-screw piercing the frog, and a threaded stem removably fitted in the'opening in the rear' end of the stick and engaging the nut to retain the frog upon the-stick, the inner end of the stem having a screw-driver blade for use in setting andwithdrawing'the screw when the frog is removed from the stick.

4. A violin-bow having a one-piece frogprovided with a passage intersecting its op- I posite ends, said passage having a tapered band wedged within one of the tapered por' tions of the passage.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

JOHN H. KANE.
